Rotary lifting mechanism in the application of C6163A type lathe

Application of rotating lifting mechanism in C6163A type lathe - 2018 11 - Luo (16 Chengdu CSR mediatek railway accessories co. , LTD. ) Bear the DF4B C6163A type lathe, DF4D, SS3B and SS7C axle half a fine car. Because the city's axle is around 2300 mm, and the quality is about 0. 6 t, lifting and turning turning, must through the crown to cooperate. In this production line, only a crown, bear the axle and the wheel lifting tasks. The car after the end, when operators need to head turning, crown may be lifting other products, can produce a lot of waiting time at this moment, which reduces the production efficiency. Through field investigation, the semi finished car axle, don't need the cylindrical turning in the end, only shaft end on both ends of the processing, processing after good end to crown lifting, switching and processing at the other end. Don't need a crown, can achieve the workpiece switching tasks, is the key point of design agencies. Assembly as shown in the appended drawings. Process: lifting mechanism will rotate through the lifting screw hole, placed on the lathe guide groove & rarr; Turn the adjusting knob v-shaped block height, so out of touch with axle & rarr; Axle by crane hoisting, through two top on a lathe clamping & rarr; Car axle end & rarr; After the car, the body move through the roller axle in middle, by adjusting the height of v-shaped block, to support the whole axle & smooth rarr; Loosen the tailstock top, move the head to tail seat & rarr; Rotary workpiece 180 & deg; , turning the clamping & rarr; Turn the adjusting knob v-shaped block height, so out of touch with axle & rarr; Car axle at the other end. Design analysis: (1) design the agency first determine machine tool center and guide groove spacing and width. (2) axle by two V block support, in order to prevent the axle, bruised when placed so the design of 100 & deg; To speak. (3) due to axle at about 2300 mm in length, to ensure the stability of axle placed, make V span lengthened as much as possible. (4) to achieve axle 180 & deg; Rotation, through the rolling bearing to accomplish. (5) to ensure the stability of rotation, through the thrust ball bearing. 6. To achieve lifting movement, done by trapezoidal thread transmission. All landowners supported the agency artifacts, try to find a balance, by two pairs of rolling bearing in the lathe guide groove mobile adjustment implementation. Today to support the upper center position can be adjusted through the lower waist shape groove, realization of V center relative to the two top center. The compact structure, strong carrying capacity, center point is adjustable. Agencies on C6163A machine tools after use, greatly reduce the waiting time for crane hoisting, virtually increased the production efficiency. （ Source: mechanic machine world)
